Large-scale experiment of co-allocation strategies for Peer-to-Peer supercomputing in P2P-MPI

High Performance computing generally involves some parallel applications to be deployed on the multiples resources used for the computation. The problem of scheduling the application across distributed resources is termed as co-allocation. In a grid context, co-allocation is difficult since the grid middleware must face a dynamic environment. Middleware architecture on a Peer-to-Peer (P2P) basis have been proposed to tackle most limitations of centralized systems. Some of the issues addressed by P2P systems are fault tolerance, ease of maintenance, and scalability in resource discovery. However, the lack of global knowledge makes scheduling difficult in P2P systems. In this paper, we present the new developments concerning locality awareness as well as co-allocation strategies available in the latest release of P2P-MPI. i) The spread strategy tries to map processes on hosts so as to maximize the total amount of available memory while maintaining locality of processes as a secondary ...
